Dear Doctor Please let me know what could be the reason for breathless ness. Why one feels that he needs more oxygen/breath. It happens several times a day when I feels breathless ness, feels that I need more oxygen but could not take sufficient oxygen inside, try to take long breath but feels like little more breath is needed to feel complete/satisfied. When ever I suffer by breathless ness, I try to complete the breath by yawning which enable me to feel better. Have gone through tests, like- MRI (spine), ECG, BP, Chest Xray, Diabetes - every thing is normal as per doctor Please let me know what is this and why this happens? Suffering since last one month but it don't happens whole day Is it curable?
